All the big players manufacture compressor oils with ISO grades. Basically, compressor manufacturers should get in board with proper wording in their lubricant specifications, and label their own branded lubricants on the shelf rigorously, too.
As for non-detergent motor oil, Castrol still makes a non-detergent 30, labeled very clearly as such. So, for those who need a non-detergent motor oil, such things still do exist.
Many electric motors which may come in contact with water stipulate non-detergent oil, heating systems being one example. I've used Mobil 1 in my boiler pump motors for decades, however, without harm.
